Abstract: Selective pre-mordanting (single and double) and natural dyeing of 6% H<sub>2</sub>O<sub>2</sub> (50%) bleached jute fabric have been carried out using myrobolan (harda) and metallic salts (patash alum and aluminium sulphate) as mordants and aqueous extract of tesu (palash flower petals) as dyeing agent under varying dyeing condition to optimize the dyeing process variables. It is found that the 20 % myrobolan followed by 20 % aluminium sulphate in sequence is a most potential double pre-mordanting system rather than using them as single mordant separately, considering the results of important textile-related properties and colour yield. Effects of dyeing process variables (time, temperature, <i style="">p</i>H, MLR, mordant conc., dye conc., and salt conc.) on surface colour strength have been evaluated to optimize dyeing conditions. Colour fastness to washing, rubbing and light, in general, and dyeing <i style="">p</i>H sensitivity, in particular, for selective fibre-mordants-dye systems have also been assessed and it is found that dyeing at <i style="">p</i>H 11 for the system offers overall good colour yield and colour fastness properties. Improvement in wash and light fastness is also achieved with suitable chemical post-treatment.
